[Some methods of assessing the work of automatic analytical systems under clinical biochemical laboratory conditions]

The use of automatic facilities at clinical biochemical laboratories involves a change in the technological pattern of the analysis. In the course of the analysis the samples pass through the same automatic devices. A transfer of a volume of the substance from a preceding sample into a vessel containing the next one gives rise to systematic errors. A procedure for measuring a volume of the substance at different stages of the analysis is proposed. Experimental data derived from an investigation of the transfer of a volume at the stages of proportioning the biological liquid and reagents when handling various types of foreign-made automatic devices are presented.
